Alexander Peden, the prophet, was born in the year 1626 in or near Sorn. Sorn Castle was a place of eminence; in 1727 it belonged to the Dowager Countess of Loudoun, and was sold to William Tennant of Poole in 1782; it was purchased by Mr. Somerville, of a mercantile establishment in Glasgow, in 1795. His daughter, Agnes Somerville, who was evidently given the usual Scottish courtesy title of Mrs. although unmarried, succeeded after the death of his son, William. She purchased Dalgain and became proprietress of about two-fifths of the parish. Graham Somerville, who succeeded her, must have been a relative, and was a man of considerable reputation. His son, James Somerville, led what might be called a rather chequered career; he was clever and might have done well, but he was quite unstable. The entail was broken and the property sold to Mr. McIntyre, who made extensive improvements to the castle and grounds and was succeeded by his son, Gordon McIntyre, Lord Sorn, one of the Senators of the College of Justice. He served with the Ayrshire Yeomanry in the 1914-18 war and was wounded.
